Montenegro's extreme temperature swings

Temperatures in Kosanica, Montenegro fluctuated dramatically on October 4 and 5, with a thirty degree Celsius difference between daytime highs and overnight lows, more than double the October average.
Clear skies drive the temperature swings
High pressure over the region brought prolonged sunshine during the day, while clear skies at night allowed heat to escape into the atmosphere without cloud cover to slow the cooling.
Low pressure system moves towards Greece
A low-pressure system is moving southwards towards the Mediterranean, deepening as it crosses the Adriatic and Ionian seas before reaching the Aegean Sea by mid-week.
Heavy rain and strong winds expected in Greece

Spells of heavy rain and strong winds are expected to sweep across Greece, with widespread rainfall of fifty to one hundred fifty millimetres forecast, highest around the island of Skiathos.
In short
Montenegro experienced extreme temperature swings last week as high pressure brought clear skies, while a low-pressure system is moving towards Greece with heavy rain expected by mid-week.
